    4555c with quality issues

    4555c Large.jpg4555c x2 Large.jpg



    The pix show prints made from the internal memory with a shaded area that sometimes shows up as staggered black lines. They also show up on the back of the page. The customer also made a comment that the prints seem to look better earlier in the day.
    Im thinking its the transfer belt cleaning assembly & transfer roller because the transfer belt looked good & the drums looked good but since Im mainly a Canon tech I thought I would ask the Toshiba experts here.

      Re: 4555c with quality issues

      I think that you'll find that the primary transfer cleaning unit has backed up, forcing the waste augur spring up out of it's trough (making those interesting patterns).

      When the auger spring lifts up out of it's trough it usually damages the primary transfer belt ... but not always.

      So, the first thing you have to determine is why it backed up: Usually because the waste bottle became overfull at the left end where the transfer waste enters. Just changing the bottle often solves this.
      Next, remove the primary transfer cleaning unit and vacuum out the chunky toner. You may discover that the unit doesn't want to come out, and that the auger spring is deformed or broken. The unit WILL have to come out. If the spring is deformed, quite often it can be re-formed into the correct helical shape, then stretched a little to stay engaged with the slotted shaft drive: 16 3/16" (or you can order a separate primary transfer cleaning assembly that does not come with the belt unit).

      At this point you should be able to make prints, and discover if the belt has been damaged. If yes, the primary transfer belt is available separately (you don't need the assembly). Then you'll have to do the color calibration.

      Did you get all that? =^..^=
      If you'd like a serious answer to your request:
      1) demonstrate that you've read the manual
      2) demonstrate that you made some attempt to fix it.
      3) if you're going to ask about jams include the jam code.
      4) if you're going to ask about an error code include the error code.
      5) You are the person onsite. Only you can make observations.

        Another thing to check for is broken clips on top of the waste toner box. We had had a few customers try to empty their WTC and break off the top 2 clips. Without the clips, the waste toner port does not open, backing up the auger spring.


        Failing to plan is planning to fail!!!

            Not sure about part number but BC meant exactly this.
            Just yesterday had to remove, clean reassemble same cleaning section on Estudio 5005ac.

              Re: 4555c with quality issues

              Yep, looks like the transfer belt cleaner spring. Several times, I've seen this, and it is JUST after they've replaced the
              waste toner bottle. You pull it out, and it's EMPTY. They let it go too long, run copies with a higher density than the
              machine "thinks" is what it should be, overfill the bottle, don't change it quick enough and the spring pops out from
              the backup. If that is what it is, make sure to take the spring completly out, clean the packed up toner from around
              the spring, and the front shaft, where it dumps into the bottle. End of a spring hook works pretty good to knock it
              out. I usually shine a flashlight into that area, just to make sure I get all the toner "rocks" out.

                    and if your customer ignores the loud noises AND the quality issues, eventually it just won't pass any paper: jam E011 ... when the transfer belt just can't turn anymore. =^..^=

                      Re: 4555c with quality issues

                      .. when that long spring eventually deforms, there is no way you can reshape and reuse it. You have to order in a whole new assembly (approx $50.00) or take one from a dead e4555c series copier.

                      Fortunately, it is an easy job taking a few minutes.

                      It is always one of the first things I check on any e4555c /e5005AC/e5015AC series copier.

                      This happens more frequently on the e2050c/e2000Ac/e2010AC copiers as the waste toner container has a much smaller capacity.

                      As a tech tip, if you are onsite and do not have a spare waste container handy, you can easily dump the contents into a garbage bag by inserting a long handled screw driver into the top hole on the back of the container. Note Messy!

                              Take a look at the black primary charge grid tensioner. It's quite common for that plastic piece to break, then the grid lays directly against the drum, making a diagonal pattern like this. In the same way, the post can break, allowing the needle electrode to lay against the grid. Sometimes you'll get a C970. The part number is: 6LK49138000 "seesaw"
